Showing my age here but...

I and some of my friends/classmates used to do the 6day 28hr cycle, to ensure we had access to the computer lab where "normal people" were asleep during the week, but were still mostly "in phase" with everybody else on weekends for socialising.

For those of you who don't understand the term "computer lab", those were the days where my Comp Sci class involved writing/running Pascal code on a shared VAX-11/780 which (from memory here) shared 64MB of memory across all users of the 100 or so terminals attached to it. During the day, especially close to assignment deadlines, there were often long wait times to get one of the terminals. If you were there (and awake) at 10pm or 4am, there was usually only a handful of other people using it, with no waiting queues and with noticeably faster performance.

(When I started 2nd year, the first year class behind me still learned Pascal, but got to use the new Macintosh lab. That kinda made the 28hr phase shifting unnecessary, but a bunch of us persisted anyway. By 3rd year, the VAX was under-utilised enough that they added a bunch of modems, and I could connect from home via a 1200/75 baud modem from the Osbourne1 Z80/CPM machine I had at home.)

He literally points out multiple upsides throughout the entire very short blog post.

Earlier quoted context omitted.

You're making some assumptions here that I don't think hold. OP is likely able to do this because they have a longer circadian cycle (though I think it's still less than 28 hours) A person who might naturally have a 24.4 hour cycle without external stimuli (which is the average sleep researchers found) will likely have problems trying to adjust to a 26 hour cycle or longer, because even if they push themselves to sta…

Do you have any recommended books or links on this topic?

I haven't read any books on the topic and don't recall any specific articles though I'm sure I've read many.

There are some good references in the wikipedia page (https://en.wikipedia.org/wiki/Non-24-hour_sleep%E2%80%93wake...), and I've been following https://reddit.com/r/N24 for a while also.

The greatest benefit is that you can stay up until you're absolutely dog-tired every day, and not have to worry about all the rituals of "sleep hygiene", like limiting screen time, dimming lights, no coffee, etc. On a >24 hour sleep schedule, you _will_ be tired when it's time to sleep. Guaranteed. Not only that, you can sleep longer and will always feel well-rested. Meeting people all around the world, when they're…

After reading the article it kinda sounds like he just takes a lot more naps. Feels like cheating.

I once changed my schedule for a month to sleeping 4 hours, waking for 4, sleeping 4, and then waking for 12. I would work in the day, come home, sleep 4, wake 4, and then sleep 4 more, then off to work again. On weekends I switched to a normal 16/8 schedule.

I got plenty of rest and got all my domestic stuff done overnight - 24h grocery store, laundromat, etc. I was never unusually tired.

The down side is that it mostly killed my social life. So I quit; the advantages didn’t outweigh the disadvantage of being on a different schedule than everyone else.

Also this was in the late 80s/early 90s before cell phones and the internet.

It doesn’t have to mean cutting people out of your life, but you’d have to be more organised in scheduling events. You’d also be unable to regularly attend recurring meetups.

I knew of a sysadmin who followed this schedule so he could monitor the system at different times of day. There’s probably the same upside for people who manage certain 24-7 operations (though the downsides outweigh them in most cases).

My brother had a friend try this in university while studying for exams and, according to my brother, it basically made the guy lose his mind. Seems like a roll of the dice on whether it works for people or not.

This seems like the biggest disadvantage to me too. I see friends four or five nights a week so I would have to give a lot of that up.

Which is a shame because longer days would probably significantly improve my sleep.

See also these internet-historical gems from everything2:

Uberman's sleep schedule - every 4 hours, sleep 20 minutes.

https://everything2.com/title/Uberman%2527s+Sleep+Schedule

Everyman sleep schedule - per above, with an additional 3-hour nap each 24 hours.

https://everything2.com/title/Everyman+Sleep+Schedule

Of course, the surest way to experiment with an alternative sleep schedule is to simply take care of a newborn, something humans have gotten pretty good at over the millennia.
